I need to swap my return crossing on 9th June on sea cat from Douglas to Liverpool at 23.45. I have a small height car booked on but need to swap for a high car as I want to take my bike in the van but it can not fit on the sea cat so I need to swap for BEN My Chree or a high car booking on sea cat for either late Friday 9th or early sat 10th to either Liverpool or Heysham. . Thanks. Keith
